Problems solved by technology

Most of the existing self-knotting products in the market have poor mechanical properties, short construction and operation time, and poor weather resistance. In addition, most manufacturers’ products contain solvents, and the construction process has a strong smell, which damages the environment and is not environmentally friendly; from the perspective of the service life of the site The quality of the products is also uneven. Some manufacturers’ products have the problem of grinding the ground floor after 1-2 years of construction.

Abstract

The invention belongs to the field of polyurethane synthesis, and concretely relates to an anti-aging self-stripped material with high strength and a preparation method thereof. The material is prepared from A and B components in a weight ratio of 1-1.5:1. The A component consists of the following raw materials, by weight percentage: 30-45% of polyether polyol A, 5-8% of a chain extender, 35-45% of a filling material, 10-15% of a pigment, 0.5-1% of a water removal agent, 0.5-1% of a thickening agent, and 0.5-1% of a catalyst. The B component consists of the following raw materials, by weight percentage: 45-55% of polyether polyol B, 40-50% of isocyanate, 1-5% of a silane coupling agent, 1-1.5% of an antioxidant, and 1-1.5% of an ultraviolet absorber. The anti-aging self-stripped material with high strength has the advantages of high mechanical property of products, long construction operation time, good weather resistance of the products and more comfortable place, and solves the problems of fading and color losing of the products. The preparation method is scientific, reasonable, and simple in operation.

Description

technical field [0001] The invention belongs to the field of polyurethane synthesis, and in particular relates to a high-strength aging-resistant self-knotting material and a preparation method thereof. Background technique [0002] The self-knotting product is a kind of self-knotting plastic surface layer that does not need to add particles. It does not need to add particles during the spraying process, and the disadvantages of particle shedding will not occur after long-term use on the construction site. Most of the existing self-knotting products in the market have poor mechanical properties, short construction and operation time, and poor weather resistance. In addition, most manufacturers’ products contain solvents, and the construction process has a strong smell, which damages the environment and is not environmentally friendly; from the perspective of the service life of the site The quality of the products is also uneven. Some manufacturers' products have the problem...
